a To all whom it may concern Be it known that I, JOHN B. VVALLAOE, a citizen of the United States, and a resident of Mukwonago, in the county of VVaukesha and State of Wisconsin, have invented certain new and useful Improvements in Attachments for Plows, of which the following is a description, reference being had to the accompanying drawings, which form a part of my specification.

My invention'relates to an attachment for plows adapted for breaking or pulverizing and leveling or, to harrow the soil as the fur-' rows are turned up; the attachment being so arranged that its action on the soil will take place while the soil is soft andbefore it has a chance to settle into its new position.

The object of the invention is to provide an attachment of the type referred to adapted to be readily secured to a walking plow, tractor plow or a sulky or riding type of plow and which will permit of adjustments suited to different types or textures of soil and therefore also to different widths and types of furrow-slices, as well as adjustment as to depth. 7

A further object of the invention is to provide a construction which will permit of the use of harrow-teeth, especially adapted for use in friable or light soils; or the use of discs where the plow is used in heavy soils; the purpose of the attachment being to thoroughly break up and level oif the thrown up soil or furrow-slice in a much more uniform manner than can be accomplished by the use of separate and subsequently operated barrows; while at the same time performing the breaking up or harrow operation-at a time when the turned-up soil or furrowslice is in better condition for such oper-. ation; the attachment, which is evident from the foregoing description and the drawings, obviating the necessity for a subsequent discing or harrowing of the soil.

Another object of myinventionis to provide an attachment whichmay be readily applied to old plows in use, or which may be permanently secured to plows while same are being constructed; andwherein the attachment, when intended for a walking plow, will have a yielding point to permit the plow to be readily removed from the soil,

, when turning at the ends of the furrows,

which is usually accomplished by throwing or inclining the plow toward the cutting side or furrow-slice.

, The objects and advantagesof'myinvem tion-w1ll be readilycomprehended from the h following detailed description of the accom panying drawings, wherein i Figure .l'is a perspective view of avwalk ing plow provided with myattachment removably secured thereto. 5'

As my invention doesnot relate to the plow per se, a detailed description of the different types of plows illustrated need not be entered into., The attachment,.as illustrated in Figure 1, is of the type. adapted to be secured to an old plow, wherein the attachment 1 is removably secured to the plow-beam 15 by means of a suitable, clamp shown somewhat in thenature of a yokeorhook member .16 adapted to extend about the plow-beam preferably ata? point intermediateofthe point where the mold-board 17 of the plow is secured to the beam :15 and the bracemembers 18 for the handles 19 are secured The member 16, in the specific exemplification of the invention, is secured in place by means of a suitable clamp-screw 20' adapted to form clamping engagement with the beam, 15 of the plow. The other end of the clamp member 16, disposed to ward-the .rear of the, plow-beam, has pivotalconnection at 211' with a beam 22 of any suitable construction, being shown in the nature of, an angle iron in Fi-gurel and of,

lengthsuflicient to extend diagonally rear;

ward ofthe mold-board and therefore-trans versely of the furrow-slice, a distance sufii cient to permit of harrow attachments-arcutting face of theplow-share and length- ,wise of the furrow-slice. In order to maintain the beam 22 with its harrow attachments down in operative position, especially where the attachmentis fsecured to a walking type of plow, the beam 22 is shown provided with a suitable clamp 23 in the nature a of a hook or sleeve portion adapted to fit over or about the beam 22, intermediate of the handles 19 of the plow; the clamp 23 being provided with a downwardly and lat, erally extending lug or extension having a suitable clamp-screw 24 which is adapted to form clamping engagement with one of the handles 19 of the plow. This will maintain the beam 22 and its attachments in proper operative position,

In the particular exemplification of the in-. vention as shown in Figure 1, the beam 22 of my "attachment is provided with a pair of discs 25 having trunnions suitably mounted orsecured tothe convexed sides of the discs and rotatably mounted'in a sleeve portion 26 at the lower ends of the short posts or members 27. The posts 27 are preferably made tubular, and are shown preferably clamped againstthe forward, flat side of the angle iron or beam 22 by means of any suitable clamping mechanism, as for example a plate 28 through which the threaded ends vof two'U-bolts 29 extend; the latter and the pl'ate28 being drawn in firm clamping engagementwith the beam 22 and with the posts 27, respectively, by means of nuts as shown in Figure 1. By making the posts 27 tubular as shown, it is apparent that the harrow attachment may be adjusted laterally through the arc of a circle concentric with the longitudinal axis of the post, when the clamp-bolts are released, thus permitting the discs 'to be arranged at the desired angularity to the line of draught and therefore to the cutting face of the plow to adapt the discsto different types or conditions of soil.

It is also apparent from the construction shown thatthe' disc 'or'discs may be adjusted lengthwise of the beam 22 to be disposed at the desired point relative to the furrow-slice; said adjustment being accomplished by loosening the nuts on the bolts 29 to release theclamping plate 28; at the same time the harrow elements may be adjusted vertically to bring them at the desired depth relative to the furrow-slice. Where the attachment is to be secured to new plows, it is evident that the attaching or clamp member 16 may be permanently or integrally secured to the plow-beam and any suitable pivotal connection provided between it and the'harrow elemerit-holding beam 22, so as to have the beamextend preferably diagonally rearward of the mold-board as disclosed in F igure l.

Where the plow is employed in friable or light soils, the harrow teeth construction,-

shown in Figure 4, may be employed instead of the discs; the harrow tooth construction comprising an attaching post or 'shank 30,

also preferably made cylindrical or tubular and terminating at the bottom in one or more right angularly disposed portions 31 apertrated a double toothed construction; the

teeth 32 bein arran ed in rsoaced relation b b and secured in the apertures of the angularly disposed arms arranged to opposite sides of the longitudinal center line of the post 30. The tooth construction, like the disc con-' struction, is intended to be adjustably secured to the beam 22 by means of the clamp ing element comprising the plate 28 and suitable U-bolts 29; the respective elements being drawn into firm clamping engagement with one another by means of nuts'secured to the ends of the bolts;

With the pivotal point arranged in the member or beam 22, it is apparent that the plow may be thrown or inclined toward the side on'which the harrow attachment is secured, namely toward the cutting side of the plow, when it is desired to release the plowpoint, as the pivotal connection 21 will permit the harrow attachment to move vertically relative to the mold-board.

In Figure 5, I disclose my invention secured to a tractor-plow, wherein the beams 34 of myattachment are preferably made of angleiron, havingtheir inner ends bent at an oblique angle and partially cut away so as to provide a fiat portion adapted to be secured against the sides of the plow-beams 35; the beams 34 being riveted or bolted to the beams 35. In order to provide suflicient rigidity to the harrow-beams 34, I have shown the inner ends of the beams bent backward into bracelike form, as indicated at '36, with the ends of the brace portions 36 riveted to the side of the beams 34. The beams 34, as clearly shown in Figure 5, will be disposed at an obtuse angle to the plow-beams 35 and arranged rearward of the mold-boards of the respective plow-shares, with the harrow element indicated at 37 arranged at suitable points on the respective beams 34 relative to'the cutting surfaces of the plows, so that the respective harrow elements will therefore be disposed at proper points relative to the furrow-slices thrown up by the respective moldboards of the plows.

In order to prevent any possible vibration of the beams or supportingmembers 34, additional brace 38 maybe employed secured at a suitable point to the supporting means boards of the respective plow-shares.

' wherein the supporting proper depth relative to the turro slices.
